Make Cheap Long-Distance Phone Calls Using your Computer
Did you know that you can use your computer to make
long-distance telephone calls to virtually any fixed line or
cellular telephone in the world via the Internet? Were you aware
that by doing so, you can save upwards of 80% in long-distance
telephone charges? Welcome to the world of 'VoIP' or 'Voice over
Internet Protocol'.
What is 'VoIP'?
Simply put, VoIP refers to the carriage of voice 'data' via the
Internet. PC to Phone VoIP refers to using your
Internet-connected computer to make calls to conventional
telephones around the world using the Internet. Whereas
traditional telephone calls take place over fixed line 'circuit
switched' networks, VoIP calls are routed through the Internet
using a far more efficient method known as 'packet switching'.
Whilst carrying voice data more efficiently via the Internet is
a benefit, the main advantage That VoIP has over the traditional
telephone networks is one of cost. For example, a typical PC to
Phone VoIP call to a telephone in the United States from
anywhere in the world generally runs at just a few cents per
minute. Keep in mind, the clarity/quality of PC to Phone calls
is usually as good and in many cases better than that of a
comparable Phone to Phone call.
How can it be so cheap?
Herein lies the beauty of PC to Phone calls. By using the 'free'
Internet to route your calls, long-distance charges imposed upon
you by the major telecommunications companies (Bell, Sprint,
AT&T, etc) are all but eliminated. Furthermore, many of the
governmental levies and fees associated with using the highly
regulated 'traditional' telephone networks are also avoided. The
result? Extremely cheap, long distance calling to conventional
telephones around the world with little or no loss of call
quality.
So how does it work?
In a typical PC to Phone call, your computer receives your voice
input via a microphone and then translates your voice into a
'data packet'. This packet of data is then transmitted via the
Internet to as close as possible to the physical destination of
the conventional telephone you're calling. At this point, your
voice 'data packet' is then switched to the conventional
telephone network and routed to the telephone that you are
calling. All of this data transmission, translation and
switching takes place transparently and extremely quickly. The
chances are excellent that the person whom you're calling would
have no idea that you're talking to them using your computer.
So what do you need?
In order to start making long-distance telephone calls using
your computer, you'll need a computer that's connected to the
Internet, a microphone and computer speakers (a headset with a
boom microphone is ideal). It's worth mentioning that although
there are several companies that support both the Linux and
Macintosh platforms (e.g., www.skype.com), the vast majority of
PC to Phone software is designed for use on Windows' compatible
PCs. As far as your Internet connection goes, the faster the
better (e.g., high speed Cable or ADSL). However, PC to Phone
does also work on dial-up Internet connections (the way I access
the Internet).
The next thing to do is choose a PC to Phone Service Provider.
These are the companies that provide the software and
infrastructure necessary for you to make calls to conventional
telephones via the Internet. There are many Service Providers
and each have their own benefits and rates so it's a good idea
to shop around. Almost all of them allow for pay-as-you-go usage
(i.e., on a per minute basis) however some also offer unlimited
calling plans to certain destinations for a low monthly fee.
Some of the better known Providers include
www.net2phone.com
www.iconnecthere.com
www.stanaphone.com
Once you've chosen a Service Provider, you'll need to open an
account and deposit funds into that account. If you're reluctant
to use your credit card online, many of the PC to Phone
companies offer alternative forms of payment (e.g., PayPal,
direct deposit, wire transfer, etc.). Next, you'll need to
download the 'softphone' application from your service provider.
A softphone is merely the interface program through which you
dial the number of the person you're calling and usually only
takes a few minutes to download on even the slowest 'dial-up'
Internet connections. Softphones generally resemble the keypad
on conventional telephones and work in much the same way.
Depending on your service provider, the manner in which you
'dial out' will vary. Typically however, the softphone will take
into account where you are in the world and adjust the dialing
settings accordingly. In other words, you'd dial the exact same
series of numbers into the softphone that you would if you were
using a conventional telephone.
Once you've made a few calls to friends and family around the
world using your computer, you'll quickly realize the fantastic
cost advantages of making 'PC to Phone' calls versus 'Phone to
Phone' calls.
So what's the catch?
Whilst PC to Phone is terrific, it isn't perfect. There are some
disadvantages that you should be aware of and these include:
a) Quality: If you access the Internet via a 'dial-up'
connection (i.e., through a normal telephone line), you may
experience call quality degradation if you are surfing the web
and talking to someone via PC to Phone at the same time. In
other words, the 'bandwidth' or 'capacity of your Internet
connection' may be limited and this could affect your calling
ability.
b) Echo: If you're using computer speakers to hear the person
you're talking to, that person may hear an 'echo' of their own
voice. This happens for reasons similar to that encountered with
the 'speakerphone' function on conventional telephones. At the
same time as you hear that person's voice coming through your
computer speakers, your microphone will also detect the voice
and re-transmit the signal back to the person you're talking to.
This 'echo' can easily be avoided by using either a computer
headset or by turning your speaker volume down so as to minimize
the chance of your microphone picking up and retransmitting the
incoming voice signals.
c) Cost: If you're calling relatively small and/or remote
countries, you should check the rates of the PC to Phone Service
Providers' to those countries before signing up for their PC to
Phone service. For example, calling a country like Fiji in the
Pacific Ocean is almost as expensive using PC to Phone as it is
using a conventional telephone. The reason for these high rates
to certain countries is due to the PC to Phone Service Provider
not having the necessary switching equipment (required for
switching your call back to the traditional telephone network
from the Internet) physically located in that country. In these
scenarios, your calls are routed through the traditional
telephone network for a good proportion of the distance they
travel and as such they attract many of the long-distance
charges that the traditional networks impose. If you'd like to
call one country in particular, it's definitely worth shopping
around to find out whether prospective PC to Phone companies
have the necessary switching equipment located in that country
(and hence, can pass on the savings to you in the form of
cheaper rates).
So give PC to Phone a try. You've really nothing to lose and
have the potential to save yourself a lot of money.
